Article
Full-text available
Reservoir compaction, surface subsidence, and induced seismicity are often associated with prolonged hydrocarbon production. Recent experiments conducted on the Groningen gas field's Slochteren sandstone reservoir rock, at in‐situ conditions, have shown that compaction involves both poroelastic strain and time independent, permanent strain, caused...

Two new three-dimensional rock mass strength criteria are developed in this paper by extending an existing rock mass strength criterion. These criteria incorporate the effects of the intermediate principal stress, minimum principal stress and the anisotropy resulting from these stresses acting on the fracture system. In addition, these criteria hav...
Article
This paper deals with two shortcomings of the smooth-joint contact model (SJCM) used in the particle flow code (PFC). The first shortcoming is the increase of the shear strength of the joint when the shear displacement of the joint exceeds a specific value that is related to the particle size. This problem is named as the interlocking problem, whic...
Conference Paper
This paper deals with the following two shortcomings of the smooth joint contact model (SJCM) used in the particle flow code (PFC): (a) Use of a constant value for joint normal stiffness instead of allowing actual non-linear behavior between the joint normal deformation and joint normal stress; (b) The so called “interlocking problem”. The first on...

Suitability of six major intact rock failure criteria: Mohr–Coulomb, Hoek–Brown, Modified Lade, Modified Wiebols and Cook, Mogi and Drucker–Prager in representing the intact rock strength under the true-triaxial stress condition (σ 1 ≥ σ 2 ≥ σ 3) is examined in this paper. Because the true-triaxial experimental test data available in the literature...
Conference Paper
Up to now, several parameters and methods such as empirical, statistical method, fractal and spectral methods are used to quantify the rock joints surface. Spectral method is the latest method and more comprehensive. One of the most useful tools in spectral method is the Fourier transform. Due to the ability of the Fourier analysis in separating si...

In rock mechanics, several researches have been contributed to the creep behavior, however, a limited number of studies have been carried out on the relaxation behavior of rocks. Impression test is a novel technique to predict time-dependent behavior of materials. In relaxation impression, a cylindrical flat ended indenter penetrates into a small r...

ABSTRACT: Most of the discontinuities and joints do not have smooth surfaces and they are covered with random distributed roughness. Finding the effective role of surface roughness on the behavior of discontinuities and on the shear strength of joints makes roughness measurement an important factor that has to be taken into account in geotechnical...
Conference Paper
Applying supports like buttresses or boughs in underground structures such as tunnels and mines cause indentation of the support into the bearing floor due to the creep, which is caused by constant load from the support. Since creep behavior is a time dependent characteristic of rocks, it is hard in practice to investigate the indentation depth of...
Conference Paper
Relaxation impression technique is a novel relaxation test in which a cylindrical flat ended indenter penetrates into a small region of sample and after keeping the displacement at a certain point, the decrease in the stress level will be recorded. Conventional relaxation test is a time consuming and expensive technique when a number of samples are...
Conference Paper
Many metamorphic and sedimentary soft rocks exhibit significant time dependent behavior such as creep and relaxation which affect the stability of rock structures. In the design of a durable structure in soft grounds, the secondary stage of creep is of paramount interest to predict the stability over long periods of time. The design of support syst...
